The results of atomistic simulations of migration and formation energies of mono- and di-vacancies in bulk tungsten are presented in our paper. The interatomic potential for tungsten was extracted with the recursive procedure from ab initio calculations of the cohesive energy. A stochastic molecular dynamics using a generalized simulated annealing procedure was employed in the simulations. Calculated values of mono- and di-vacancies energy parameters are in a good agreement with experimental data and with the results of other calculations.
